[PATCH 00/13] some stuff, and then connector_list locking

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I finally clued up about connector_list locking and here is a fix for that
little issue that's not totally horribly nightmare fuel. As usual I ended up
reading too much other code, so there's a few random bits in here too. Some of
the earlier randomness I submitted already and it's in drm-misc by now.

Anyway, core is all fixed up (and lost 2 FIXME and all unprotected
connector_list walkers). Helpers are converted (again all of it), plus i915 as
an example. Well, not all: The ones in intel_display.c look like (at least some)
that they should instead walk the connectors in some atomic update. An I just
couldn't be bothered to change the code in intel_sdvo.c since meh. Otherwise all
the existing connector_list walkers (whether drm_for_each_connector,
for_each_intel_connector or raw walk) are now all connected.

Seems to not immediately blow up, and even after a few nights of sleep I still
think this is correct.

Kerneldoc is also polished and updated.

Feedback and review highly welcome.

Cheers, Daniel
